Chainsaw restoration

I have been using the Rust-Oleum Camo spray paints to do custom paint jobs on chainsaw's.

I currently have a 1958 Homelite EZ chainsaw that I would like to restore. This saw was my grandfathers. There are others that have been trying to replicate the color of paint on these and other chainsaws.

If I was to supply a small piece of orignal paint I found while taking this saw apart, would Rust-Oleum be able to replicate it?

Or is there a way of using current products (in a specific order) to replicate this color?

I am including a picture of one chainsaw I did for my uncle who is a retired Army Ranger.
